Lewes Circular River Walk

This circular walk around the county town of East Sussex includes riverside paths, lovely views of the South Downs and a visit to Lewes Castle. The attractive town is located a few miles north east of Brighton, in a pretty area of the South Downs.
As such there's several good options for walkers with some good hill climbs and waterside walks along the River Ouse to enjoy.
Walk Report October 14th 2026 By Claire Bennett:
I’d been meaning to explore more of the countryside around Lewes for a while, so this circular walk seemed a good way to combine a bit of local history with some quieter riverside walking.... Lewes is a lovely old Sussex town, with its castle above the High Street and the South Downs rising around the edges of the valley. It’s also only a short distance from Brighton, but once you leave the busier streets behind, the pace changes considerably.
I started at Lewes Castle, which dates back to the years following the Norman Conquest. Its position makes sense when you look at the surrounding landscape: it stands above the town near the gap in the Downs carved out by the River Ouse. From there, I walked along the High Street towards the river, passing the independent shops and historic buildings that give Lewes so much character. It’s worth taking your time through the centre rather than treating it simply as the way to the countryside.
Once I reached the river, I joined the Sussex Ouse Valley Way and followed the Ouse north towards South Malling and Offham. This was my favourite part of the walk. The river winds through a broad, open valley, with the water, grassy banks and distant chalk hills creating a much more peaceful atmosphere than the town centre. I found myself slowing down to watch the river and look for movement among the reeds rather than worrying about making quick progress.
The stretch beside Offham Marshes is particularly good for anyone interested in birdlife. The wetland habitat attracts mallards, mute swans, grey herons and moorhens, and it’s worth keeping your eyes open along the riverbank rather than concentrating only on the path ahead. I spotted a heron standing almost motionless near the water, looking as though it had all the time in the world. After the recent rain, some of the softer sections underfoot were a little muddy, so decent walking shoes were useful, although the open views made this a very enjoyable stretch.
Offham itself provides a change of scene before the route turns back towards Lewes along the Greenwich Meridian Trail. I liked the contrast between the riverside walking and the quieter countryside on the return leg. The trail follows the line of the Prime Meridian, the imaginary line separating the eastern and western hemispheres, which adds an interesting geographical twist to an otherwise gentle country walk. The surrounding fields and views towards the Downs are a reminder of how quickly you can get out into open countryside from the centre of Lewes.
There’s history here beyond the castle, too. The area around Lewes was the setting for the Battle of Lewes in 1264, when Simon de Montfort’s forces defeated King Henry III. It’s fascinating to think that these peaceful fields once formed part of a major conflict in English history. You don’t need to make a separate historical detour to appreciate how closely the town and its surrounding landscape are connected.
Back in Lewes, I was glad to have left time for a wander through the old streets before heading home. The Swan Inn on Southover High Street is a tempting place to stop for a drink or something to eat, with its traditional interior and walled garden. Overall, this is a rewarding circular walk that mixes town history, birdwatching and easy countryside miles without needing to drive between different locations. I’d allow time for stops along the river, especially if you enjoy watching wildlife, and would happily return to explore more of the Ouse valley.

Pubs and More Info
Back in the town head to the Swan Inn for some post walk refreshment. The quaint little pub serves good quality food and has a delightful walled garden for warmer days. The historic inn dates back to at least 1760 and has a charming interior with low ceilings, wonky walls and an open fire. You can find them at 30a Southover High Street with postcode BN7 1HU for your sat navs.
To continue the walk you could follow the river in a southerly direction and visit the village of Rodmell. Here you can pick up the South Downs Way long distance trail.
One of the higlights of the area is the nearby Mount Caburn. Here you will find a lovely nature reserve and wonderful views from the 480-feet (146m) hill summit. Our Glynde to Lewes Walk will take you there on a circular path while also visiting the historic Glynde Place.
Another good option is to follow the Sussex Ouse Valley Way in a north easterly direction to Barcombe Mills. Here you can enjoy waterside trails, a small reservoir and a delightful riverside pub.
Another major highlight of the area is the climb to Firle Beacon.
Just a couple of miles to the south you'll find the interesting village of Iford. The historic settlement includes 18 listed buildings, a 12th century church and a sundial marking the Greenwich meridian which runs through the village. From here you can enjoy a walk up to the viewpoint at Iford Hill on a particularly lovely section of the South Downs. On the Iford walk there's also Rodmell where you can visit the National Trust's Monk's House. The 16th-century weatherboarded cottage was once the home of author Virginia Woolfe and her husband. Next to the village there's also the Castle Hill National Nature Reserve. The significant site includes chalk grassland with ancient settlements and lots of interesting flora and fauna to see.

Lewes Castle. The medieval castle's original name was Bray Castle, and it now stands in a commanding position guarding the South Downs gap between the towns of Lewes and Cliffe. It is made of local limestone and flint blocks and is built on a man-made mount just north of Lewes' high street.

Site of the Battle of Lewes 1264. The battle was fought between Simon de Montfort and Henry III in the field in the foreground with the former being victorious. This stunning view takes in Lewes, Lewes castle, Southerham chalk pits to the left and Beddingham Hill behind it. Nearby is the Battle of Lewes Memorial. Presented to the town in 1964 on the 700th anniversary of the battle and placed in the grounds of the former priory.

Cliffe High Street, Lewes. Looking east towards the junction with Malling Street and South Street. Until the 1960s this was the main road out of Lewes. Cliffe has long been a suburb of Lewes and grew out of its position as a crossing point over the river Ouse. It's still a shopping street but the eastern end thankfully is full of smaller shops rather than the big chain stores. Unfortunately, the area is still susceptible to flooding the last causing widespread damage a few years ago. This whole street was under water.
